PetMeds® Bald Spots on Pets – Potential Causes

In most cases, bald patches are often due to allergies including inhalant/contact allergies and/or food allergies.Patchy areas of hair loss or bald patches on our pet’s coats are common findings on physical exams.  One of the first things a veterinarian will do is to examine the hair shafts under the microscope to see if the hair loss is from self-licking or trauma from the pet. Further testing may include skin scraping to see if there are any mange mites, as well as fungal cultures to see if there is any yeast or ringworm causing the hair loss.

In most cases of self trauma, bald patches are often due to allergies including inhalant/contact allergies and/or food allergies. With such a thorough diagnostic workup, most cases of bald patches can be properly assessed and treated.  That is why it is always important to have a full veterinary evaluation first before self treating such lesions on our pets.

  1. need help with my daushound he is 6 yrs old he has some bald spots on his back dont know what to do for him

  2. I would first do thorough flea comb check to make sure no fleas around, and in case bald spots are due to flea bite allergy which are common presentations of lower back hair loss in dogs. Other possibilities include other types of allergies such as what i call Doggy Hayfever or canine atopy, which is contact/inhalent allergies to molds, grasses, trees, ragweed, dust mites, pollens, etc as well as food allergies. He may have secondary bacterial and/or yeast infections, as well as possibly underlying hormonal issue like thyroid or adrenal issue causing hair loss. Only full vet workup can sort all of these out and best treatment plan. You can start with supplementing his diet with Be well fatty acid supplement from 1800petmeds, as well as adding enzyme to meals like naturevet enzymes

  3. My dog has quarter-sized bald spots on his back. The skin appears dry and a bit flaky. The vet said he is allergic to something. He is 5 years old and has eaten the same brand of food all this time so how could be now be allergic to it?
    He is not itching those bald spots but they look horrible.
    Is there a cream for bald spots on dogs?

  4. Hi Linda. Food is only one type of allergy, and is the least common of the allergies seen in dogs. More common flea bite/insect allergies and/or contact/inhalant allergies may be involved. Your pet also may have a localized secondary bacterial infection of the hair follicles also involved which may need prescription antibiotics from your vet. For now, you could try topical neosporin on these spots, but best to check with your local vet for appropriate prescription topical and/or oral antibiotics, etc

  5. I have a 7 yr. Old ragdoll with flea allergies, and had some dry patches and an overall thinning of his fur, and about a 3 inch balding tail starting at the base of it and was always scratching , I gave him a 500 mg fish oil for about 6 weeks, now I give it to him every other day since he hates it so much! But wow his fur is grown in thicker,longer and shiny! What a beautiful transformation!
